DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to FIG. 1, an electric vehicle rescue system 100 is illustrated that can tow a disabled electric vehicle (EV) 105 and charge it during transport to a destination. The rescue system 100 can include a rescue vehicle 110 that includes a mobile platform 111 including a winch 112 and a ramp feature 113. The platform 111 can operate as the ramp by mechanized tilting of the platform 111 toward the ground in front of a disabled vehicle as shown by dashed lines in FIG. 1, or a separate ramp section (not shown) can be deployed from the platform. It is typical today for the entire platform to be manipulated away from the rear of a truck as a rescue vehicle 110 to place the platform 111 in front of a disabled vehicle 105 that is requiring towing or transportation. It is preferable today that the mobile platform 111 of the rescue vehicle 110 is deployable into an angled position in contact with the ground for retrieving a disabled EV 105 (as the “rescued vehicle”) thereon by operation of a winch 112, which is typically connected to a tow hook, or the like, located near the front of a disabled vehicle 105 as the rescued vehicle is mechanically pulled onto the platform 111 by the winch 112. Once the rescued vehicle 105 is in place on the mobile platform 111, it is secured with straps or chains for transportation.

A charging unit 120 is included in association with the electric vehicle rescue system 100 for connection to and charging of the EV 105 by connection to the EV's connection port 115. Charging of the EV 105 can occur either on location or during transport of the EV on the mobile platform 111. A customer can be charged separately for charging and transportation, depending on the elected service.

A systems analysis module 130 can also be included in association with the an electric vehicle rescue system 100 for testing the functionality of systems and components of the EV 105, either on site or during transport of the EV 105 on the mobile platform 110. The system analysis module can be connected to a test port (not shown) that is typically provided in a compartment within the EV 105. Results of analysis can be provided to customers in printed form or electronically via a data network. A customer can also be charged separately for the analysis.

It should be appreciated that the mobile platform 111 can be provided as a rescue vehicle in the form of a trailer pulled by another vehicle (e.g., pulled by a heavy duty truck) or integrated with another vehicle (e.g., the truck 110 as shown). It should be appreciated that the electric vehicle rescue system 100 can also include the ability to carry passengers associated with said EV as the EV is being transported, charged, and/or analyzed by the rescue vehicle. For example, the mobile platform 111 can be integrated or installed onto the back of a heavy duty, four door 107 (e.g., crew cab) truck that can also function as a shuttle for paying passengers.

It is also a feature of the present invention that the rescue vehicle can include means for charging batteries associated with the rescue vehicle or the rescued vehicle. The means can include at least one PV panel associated with the mobile platform 110 to charge batteries when a vehicle is not being transported. A generator 140 can also be associated with at least one of the wheels 145 (or axles) of the rescue vehicle and can generate power as the rescue vehicle is moving on a road or highway while transporting a rescued vehicle. The time that it takes to charge an EV is dependent on the amount of amperage and power that can be provided by the charging system. There are currently Level 1, Level 2, and DC charging stations available at stationary locations. The DC charging stations, such as the 480 volt DC CHAdeMO fast charging stations, are the highest power systems available today, are a three-phase system, and can charge an EV as soon as 20-30 minutes; however, significant power must be generated to accomplish fast charge. On a mobile platform, fast charge can also be accomplished if additional means for generating power as described herein are provided, and if a bank of batteries is available on the platform to transfer DC charging energy to the EV batteries. Any variation of solar panels, generators, and batteries can provide enhanced charging capabilities for the rescue vehicle.

Retrieval, transport, charging, and analysis are features that can be offered to disabled vehicles as part of a roadside assistance program. Referring to FIG. 2, it is also a feature of the present invention that a roadside assistance service incorporated an electric vehicle rescue system 100 as described herein can be provided via a network of independent providers 230 that can be connected to stranded EV customers 220 using a mobile application accessed by providers and customers alike, and the provider and customer matching and transaction are managed by a remote server 1300 via a data network 1400 and matching is based on physical location (e.g., GPS, or triangulation based on cellular network towers 250) of the independent providers and the stranded customer making a request. Apps, such as UBER and LYFT are available on mobile devices to hire transportation from point A to point B for a customer. However, there is not a similar app that can match rescue vehicles with vehicles in need of rescue.

Referring to FIG. 3, a method in accordance with features of the present invention is illustrated. Referring to block 310, a customer connects to a remote server via a mobile application to request vehicle rescue services. As shown in block 320, the server determines the requester's location and locates service providers near the requester. As shown in block 330, the requester selects a service provider to provide rescue services. As shown in block 340, the selected service provider accepts the request. Then as shown in block 350, the service provider bills the requester upon completion of services including at least one of EV charging, EV transportation, and EV analysis.
